Technetium is a by-product of the nuclear fission of 235U. There are a lot more nuclear reactors now compared to the 1950s. -Sloonei
Technetium has become less expensive due to advancements in nuclear technology, specifically the development of more efficient methods for producing it in nuclear reactors. Additionally, increased supply from reactors and recycling programs have helped reduce the overall cost of technetium production.
Because it's easier to rpoduce now, people know where it is and how toproduce it.
The production of technetium has grown and the technology of preparation was improved.
An important cause is the improvement of the preparation/separation procedures.
Technetium is odorless.
Technetium is not "radiographic" but it is radioactive.
The chemical symbol of technetium is Tc.
Technetium hasn't odor.
All isotopes of technetium are radioactive. Technetium is found only in trace quantities in nature, and then usually only in certain ores where it is a product of radioactive decay. All of the technetium used is synthetic.
Technetium-99m is largely used as tracer in radiodiagnostic.Technetium-99 is used as standard source for beta radiation. Technetium-95m is used as tracer in environmental studies.
Technetium is a radioactive element that is not present in nature in appreciable quantities, so it does not have a specific odor associated with it. Its radioactivity means that exposure should be minimized and strictly controlled.
The price of technetium has gone down because there wasnt much technetium in the 1950s which made it rare and expencive but now there are more power stations now than there was before which produce technetium so there is more about and has reduced in price.
As opposed to what? Technetium is pretty much the radionuclide of choice for most nuc med scans, it's got a good energy (140 kEV), a low half life (6 hrs) and it's cheap and readily available.
Technetium is odorless.
Technetium is not from Japan.
Technetium is a metal.
Technetium is a radioactive metallic element with no known taste or flavor. It is not naturally occurring on Earth and is primarily produced in nuclear reactors.
The Brinell hardness of technetium is 112.The Vickers hardness of technetium is 151.
its a metal
Technetium is not a material to be sold to anyone on the counter.
Technetium is paramagnetic.
